CT Errata Compendium

[rancke]

As for the TNS quote Hans cited, drop tanks begin its service in the core (and so we assume in the Imperium) at about 1092...

That's more precise than I've been able to date it. How do you arrive at that date?

JTAS 4, in the Gazelle example it gives, says the unicorn was laid down in 105-1084, and made its first flight in 098-1086 (JTAS 4 page 20), about 6 years before drop tanks began to be used (and it was not the first Gazelle built, as is hinted in many places)...

I once worked out a guestimate for the building of the Gazelle that has it laid down on 131-1079 with a first flight on 242-1080. Details here and in the associated meta-data.

I see no way to justify the Gazelle design without its use of drop tanks...

The Gazelles are military, the drop tank service alluded to in the TNS newsbrief is civilian. Presumably the Imperial Navy kept the technology restricted for some time (For as long as they could possibly stave off commercial interests is my guess, although I don't know how long that would be).

Yourself posted it... In 1105 the TNS says it has been in use in the core for the last dozen years, so I just substracted 12 form 1105. I know this is a guestimate too, but I thought it was a logical one.

Yes, it is a military ship, but I don't believe it was designed by IN if its first example was laid down in 1079. For then, IN had TL 15 for about 80 years, and I guess In was not longer designing TL 14 ships, as they would design them better at TL 15

 

[Matt123]

I think treating DT's in the same manner as the question "can fighters be launched before combat starts" is probably the best answer. Give a little background and errata that the ref or players should agree on an answer before play.

TL14 (& TL13) Imperial ships can be built in more locations, spreading the Imperial budget to more worlds. Might pay to start a new thread though if you wish to debate this view... Otherwise we are cluttering Dom's errata thread.

I don't think it's worth a dedicated thread, but forgive me for just an answer more (if I see more replies are needed, I'll think about your suggestion).

If the Gazelles were designed for non-imperial Navies (planetary/subsector-reserve), then they will not be allowed to use technology that the IN tried to keep restricted (how long would it be so then), as Hans appointed as a possibility, so, IMHO, we're again were we started: there's an incongruency here that should be clarified about when drop tanks began to be used.

New CT errata (0.06) posted to my website.

 

[Dragoner]

Book 1 (1981) page 47, Body Pistol should be Close +1, Short +2 on the range matrix similar to the other pistols.

Book 4 page 39, no extreme range or TL is given for the VRF Gauss Gun (usually I use 2000m, same as the Auto-Cannon and TL10 from the table on page 52).

I don't think so; all other sources (TTB, ST, Snapshot) appear to match the given values. I'm open to more discussion.

Book 4 page 39, no extreme range or TL is given for the VRF Gauss Gun (usually I use 2000m, same as the Auto-Cannon and TL10 from the table on page 52).

I think the Extreme Range should be 4500m (?), if I'm looking at Striker right. Anyone else with Striker confirm? The TL 10 is supported.

 

[Tobias]

The German version of Mercenary (in the German Book Traveller II) has an extreme range of 3km for the VRF Gauss.

 

[Dragoner]

I don't think so; all other sources (TTB, ST, Snapshot) appear to match the given values. I'm open to more discussion.

Having fired the Walther PPK (the equivalent given in Bk 1), and owning a CZ 85B (a DA Browning Hi-Power type); at close range, which is listed as touching, there is not any difference. In fact automatic pistols you don't want to use so close, as muzzle contact can push the slide back taking the pistol out of battery.

I think the Extreme Range should be 4500m (?), if I'm looking at Striker right. Anyone else with Striker confirm? The TL 10 is supported.

Seems long compared to the other Bk 4 ranges, also it is firing the same Gauss Rifle 4mm 4g projectile, so terminal ballistics would be comparable, losing energy rapidly over distance without greater mass to help retain velocity.

Edit: after looking into it, even the GR comes out at 500m with negligible energy (>0.13nm), so whatever range is fine.

Umm - No!

Umm - No!

What do you mean?

 

[christopher.boote]

Marc has said (in a number of places) that Jump-capable torps are a no-no in Traveller
A 100+ ton vehicle can jump, a 99- ton can't

And canon twice rejects that assertion.

TNE has jump boats; they figure jump performance as if 100Td, even tho' they are smaller. (Minimum is thus Computers, Bridge, 10Td Fuel, 2Td JDrive, 1Td other drives - in TNE, that means 20Td or so. I can't get to my FF&S to do the actual numbers.)
CT has Jump Torps. They are in the core rules in some pre-CT2E printings, and in Leviathan.

Note that, really, there are about 7-10 different editions of CT.
Broadly, tho:
CT 1E has no PP requirement for JD, and damages in dice+adds. Except for the standard designs, it's been decanonized - but it explains the CT X-boat.
CT 2E has PP minimum for JD, and damages in even dice.

Several printings of 1E have Jump Torps, and some have the Route Generation Table. Other minor changes from printing to printing exist.

 

[77topaz]

A torp-like vehicle just has to be big enough to have a J-Drive, M-Drive and AI. Surely those don't add up to 100t alone?

In TNE, there is a volume with automation rules... but I never bought Vampire Fleets (as I hated Virus as a dispeller of willing suspension of disbelief).

However, the requisite tonnage for the 100Td affected area minimum is:

_1Td computer
_2Td JDrive
10Td JFuel
~1Td Structure, PP, and PP Fuel

So about 14-15Td.

Doing it in MT, the Computer can be the AI, so only about
≤_3_kL Robot Brain
__4_kL 2x Model 1
135_kL JFuel
_27_kL 2xJD units
__2_kL TL10 4 MW minimum fusion plant. (0.01_kL/Hour.)
__2_kL 200 hours op time.

For 13 Td. Add a small SR for 2Td more, swapping out the robot brain for another Model 1, a pair of control panels, and some AG and LS. Another ton and you get 2G performance.

A 20 TD unit can have some useable capacity, manned.

This thing can safely run Everything at once, as it has about 10 MW surplus The big draws being LS, MD, and Sensors. By adding a 2 kL minimum volume plant, at 4 MW, the LS and computers can be run for 1/7 the fuel cost… giving 168 hours jump time and 176 hours system time - a standard jump cycle - or considerably more coasting time.) It needs some 226 CP, and has 230 post computer. I've intentionally not figured mass - I'm lazy.

It's about MCr25, carries one guy comfortably, two in very friendly conditions (albeit a bunk could be installed for the 2nd guy, and a 3rd hotbunking with the first in the SSR.).

Of course, this requires that the TNE example dodge of figuring a jump-craft as needing a 100Td capable JDrive is valid...

 

[DonM]

Guys, I'm sort of trying to catch up... some of this does not appear to be CT errata... or is it?

 

[Hyphen]

A torp-like vehicle just has to be big enough to have a J-Drive, M-Drive and AI. Surely those don't add up to 100t alone?

There's three options discussed on my website.

Go to the Repair Bays, Canon Problems, then the Jump Torp page.

Didn't know that 'dodge' (but then I never went near TNE)
So as long as it's got the J-drive to move a 100t J-1, and the PP-drive to support that, a sub-100t jump capable ship is legal in TNE?

Any caveats like <100t is unsuitable for sophont travel? Does it need J-fuel and PP-fuel as if it were a 100t ship as well?

Otherwise you can easily make a 40- or 50- ton xboat (depending how close you want to stick to LBB2)

 

[christopher.boote]

Well, if Jump torps are legal, it isn't
If they aren't, it is
